I was expecting a `,' or a `}'BibTeX

I apologize for the confusion. It seems that you are encountering an error message related to BibTeX. The error message "I was expecting a `,' or a `}'" typically occurs when there is a syntax issue in your BibTeX file.

To resolve this error, you should check your BibTeX file for any missing or misplaced commas (`,') or closing curly braces (`}'). Make sure that every field in your BibTeX entries is properly enclosed within curly braces and separated by commas.

Here's an example of a correct BibTeX entry for a book:

@book{example,
  author = {Author Name},
  title = {Book Title},
  year = {2021},
  publisher = {Publisher},
}

Make sure that each field is enclosed in curly braces and separated by commas, and that there are no missing or extra characters. Also, check for any unclosed parentheses or quotation marks that could be causing the error.

If you can provide more specific information or the exact BibTeX entry that is causing the error, I can assist you further in identifying and resolving the issue.
